Application filed July 14, 1919. Serial 1%. 310,787.

To all whom it may concern 7 Be it known that I, Gnonen J. (ionsnon, a citizen of the United Eitates, residing at Rochester, in the county of Monroe and State of New York, have invented certain tor Upper-Forming Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to work position ing means for upper forming machines used in the manufacture of boots and shoes, and is herein illustrated by reference to its use in a macl'iine designed for molding the heel end portion oi? upper materials, although it to be understood that the invention is not limited in utility to machines for performing molding operations nor to machines tor operating on the heel end portion oi: the upper. It is also to be understood that the invention is not limited to use in combination. with an abbreviated shoe end form as herein shown, and that the term shoe form as hereinafter used, unless required by the context, imports no limitation with respect to the specific character of the means over which the upper is to be shaped.

Upper forming machines heretofore in use have been provided with various devices designed to assist the operator in determining the correct relation of the upper to the form in order to provide the required width of margin to be wiped inwardly over the bot tom face of the form. Such devices have been open to various objections, as opposing, for example, an obstruction to the proper manipulation oi the work or to the operators view of the work, or as failing to afford a sufliciently positive and reliable means for gaging the location of the upper. The present invention provides a novel construction herein shown comprises a plurality of gage members arranged to project beyond the edge of the bottom face of the form at the end and at the opposite sides to serve as abutments for positive engagement with the edge face ofthe upper materials in the several locations, thus contributing to speed and accuracy in the presentation and adjustment of the work. In the illustrative con struction, moreover, the several members are supported on the form for movement outwardly to operative position after the upper has been placed about the form and for return movement to an idle retracted position in response to pressure of the mechanism which wipes the margin of the upper inwardly over the term. Jl\.lll1()l1ltttl0 means is thus provided for locating the gaging the upper beyond the plane oi. the bottom face ot' the form as between the end and the opposite sides of the form. V

The various novel. features of the invention, including the more important details of construction and combinations of parts, will now be more particularly described with reference to the aceon'ipanying drawings and pointed out in the claims.

In the drawings,

Figure 1 is a perspective view of a portion of an upper forming machine including up per positioning means constructed in accordance with this invention,

Fig. 2 is a longitudinal vertical section through the heel end form shown in Fig. l with thework positioning means shown in side elevation, and

Fig. 3 is a plan view showing the work positioning means in its retracted or idle position. c

For convenience the invention is herein illustrated in its application to a type of upper forming machine such as shown in United States Letters Patent No. 1,197,439, granted on September 5, 1916, upon an application of Matthias Brock. This type of machine includes in its organization a heel end form 2 over which the heel portion of an upper 41!, is to be molded, an outer form or molding device comprising a heel embracing band 4 which is closed about the upper around the end and sides of the form 2 with molding pressure,and end embracing wipers 6 which are secured to carrier members 8 and are advanced and closed inwardly by these members to wipe the margin of the upper materials over the bottom face of the form 2 and. to moldthem into an inwardly projecting flange. For the purposes of this invention, a supporting plate 10 which is dovetailed to slide in a guideway extending lengthwise of the bottom face of the form 2 has mounted thereon a gage member 12 which is adapted to extend over the edge of the upper materials at the rear end of the form and additional gage members 14 which are'arranged to extend outwardly over the edge of the materials at the opposite sides of the form at a considerable distance from the heel end. For supporting the members 12 and 14 a plate 16 is provided, this plate being connected at one end by a horizontal pivot 18 to the head portion of a pin 20 which extends downwardly through the plate 10 and is adapted to engage in a recess 22 in the form. Near its opposite end the plate 16 rests normally upon the upper end of a pin 24' which likewise extends downwardly through the plate 10 into a recess 26 inthe form. The gage member 12 is guided for lengthwise movement on the plate 16 by means of pins 28 which are fast on the plate and extend through slots in the member 12, these pins having heads which overlie the member and prevent its'displacement. Midway of its length the member 12 is recessed underneath to receive the members 14 which are connected together and to the member 12 by means of a pivot pin 30. The members 14 are guided andcontrolled in their inward and outward movements by pins 32 which are fast on the plate 16 and project through slots in the respective members, these pins having heads which overlie'the members 14 and serve as additional means to prevent their displacement. A pin 34 which is fast on the supporting plate 10 projects upward loosely through the plate 16 and through one of the slots in the gage member 12 and is provided at its upper end with a spring 36 which bears downwardly upon a washer 38 infrictional engagement with the member 12. The spring 36 thus applies pressure frictionally against the member 12 sufficient to guard against accidental displacement of the member from its operative or its inoperative position, the degree of pressure applied to the member being adjustable by means of a nut 40 on the pin It will be seen, by reference particularly to Fig. 2, that the pins 20 and 24 position the plate 16 and the supported gage members 12 and 14 at the proper distance above the bottom face of the form to permit these members by their outward projection beyond the edge of said face to serve as abutments for engagement with the edge of the upper niaterials and thus to determine the proper height of these materials to provide the correct width of margin to be wiped inwardly over the form. The pins are adjustably mounted in the plate 10 and in upstanding projections formed on the plate, and may he moved upwardly or downwardly to vary the height of the gage members. By relative adjustment of the pins, moreover, the plate 16 may be tipped to effect a relative variation in height between the outer end of the member 12 and the members 14, such an adjustment being sometimes desirable where the best results require a variation in the extent of projection of the margin of the upper as between the end and the sides of the form. Set screws 42 serve to retain the pins in adjusted position. It will be understood that in order to permit removal of the plate 10 and its supported mechanism from the form the pins 20 and 24 are to be raised a sufficient distance to withdraw their lower ends from the respective recesses 2-2 and 26.

In the normal position of the mechanism above described, prior to the use of the ma chine upon an upper, the gage members 12 and 14 occupy a retracted position, as shown in Fig. 8, the outer ends of these members thus being withdrawn inwardly from the edge of the bottom face of the form to permit the upper to be placed freely over the form. Having positioned the upper on the form with its bottom edge below the plane of the gage members, the operator by a quick movement pushes against the rear end of the member 12 and slides it outwardly into the position shown in Figs. 1 and 2, the members 14 being simultaneously swung outwardly by reason of their connection to the member 12 and their relation to the guide pins 32. All three members are then positioned to serve as abutments for engagement with the edge face of the upper, and by moving the latter upwardly over the form 2 the operator positions its edge against all three members which automatically determine its correct location. While holding the upper in this position, the operator starts the machine and the several molding operations are effected in the usual manner. hen the wipers 6 are advanced to wipe the margin of the upper inwardly over the form, the carrier members 8 engage the outer end of the member 12, and it may be also the ends of the members 14:, and move the several members inwardly to their idle position. Automatically operative means is thus afforded for returning the gage members to the position illustrated in Fig. 3, where they remain while the work is withdrawn from the form and until after the operator has mounted another upper upon the form.

The spring 36, in addition to its function hereinbefore described, serves additionally as yieldable means against which the plate 16 and the gage members may be swung upwardly about the pivot 18 in case undue pressure is applied by the sloping front edges of the carriers 8 against the members 12 or let after the gage members have been forced to their limit of inward movement.
